Description
One, technical field: the invention belongs to advertising lamp box, relate in particular to a kind of light body, at the same position lamp box of changing patterns regularly.
Two, background technology: at present, advertising lamp box is various in style, and the transformable lamp box of picture occurs in recent years successively, its principle is the back of grizzly bar shape shielding plate, by a width of cloth by several patterns to scheme the compound picture that strips is formed, when doing relative displacement with the front grid, the transparent part of grizzly bar shielding plate will present the width of cloth in several patterns.But at present all there is problem bulky, that structure is heavy, cost is higher, picture fold, pattern are easy to wear, poor reliability etc. has a strong impact on use in existing this type of lamp box.
Three, summary of the invention:
1, goal of the invention: the invention provides a kind of light picture-variable lamp box, its purpose is to solve in the past advertising lamp box and has problem bulky, that aspects such as structure is heavy, cost is higher, picture fold, pattern are easy to wear, poor reliability exist.
2, technical scheme: the present invention is achieved through the following technical solutions:
A kind of light picture-variable lamp box, it includes casing, be arranged on transparency window on the casing, be arranged on light source in the casing, all tabula rasa, stator, it is characterized in that: be provided with a motor in the casing of profile shapes, the gear shaft that links to each other with motor is meshed with the gear bar, and the gear bar is connected with pull bar, be fixed with the ladder slide block on the pull bar, the ladder slide block is provided with roller, and roller is connected with a moving plate by coupling arrangement, and the lower end of moving plate is articulated in the bottom of lamp box by the moving plate back-moving spring; The upper end of stator is by with after the film clamp bar of its identical coefficient of thermal expansion is fixing, and 180 ° of angles tilings of warpage downwards.
Between moving plate and stator, back and forth be wound with tension lines.
Coupling arrangement below the roller is that a U type hanger is connected with the moving plate screw rod, adjusts nut, moving plate hangers.
The lower end of stator connects a box-like spring, and box-like spring is arranged in the spring base.
On pull bar, be provided with displacement detecting and controller.
3, advantage and effect:, can solve existing advertising lamp box well and have problem bulky, that aspects such as structure is heavy, cost is higher, picture fold, pattern are easy to wear, poor reliability exist by enforcement of the present invention.And, being slidingly matched because of the minim gap of palisade shielding plate and compound picture is the key of this equipment, this just makes the problem that has been fixed into of the very big film of coefficient of thermal expansion and other member, being connected with frame material or glass plate is present common way, and its critical defect is can produce serious fold and make the pattern confusion through film after the several temperature heave period.The technical solution used in the present invention just can solve this difficult problem effectively, and single square meter weight only is equivalent to 1/3 of existing this product.Lightness design because of inner structure makes the power draw of power system reduce 70%, has reduced cost significantly, has improved cost performance, and picture is easy to change, dependable performance.
